The influence of circumnuclear environment on the radio emission from TDE jets [PDF]
, 2016 Dozens of stellar tidal disruption events (TDEs) have been identified at optical, UV and X-ray wavelengths. A small fraction of these, most notably Swift J1644+57, produce radio synchrotron emission, consistent with a powerful, relativistic jet shocking ...

Radio jet interactions in the radio galaxy PKS 2152—699 [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 We present radio observations of the radio galaxy PKS 2152-699 obtained with the Australia Telescope Compact Array (ATCA). The much higher resolution and s/n of the new radio maps reveals the presence of a bright radio component about 10 arcsec NE of the nucleus.

A Panchromatic View of Relativistic Jets in Narrow-Line Seyfert 1 Galaxies
Galaxies, 2016 The discovery by the Large Area Telescope on board Fermi of variable γ-ray emission from radio-loud narrow-line Seyfert 1 (NLSy1) galaxies revealed the presence of a possible third class of Active Galactic Nuclei (AGN) with relativistic jets in addition ...

Tracing the extreme interplay between radio jets and the ISM in IC 5063 [PDF]
, 2013 We report the discovery with the Atacama Pathfinder EXperiment (APEX) of an outflow of molecular gas in the radio-loud Seyfert galaxy IC 5063 (z = 0.0110).

INVERSE DEPOLARIZATION: A POTENTIAL PROBE OF INTERNAL FARADAY ROTATION AND HELICAL MAGNETIC FIELDS IN EXTRAGALACTIC RADIO JETS [PDF]
, 2012 Motivated by recent observations that show increasing fractional linear polarization with increasing wavelength in a small number of optically thin jet features, i.e., “inverse depolarization,” we present a physical model that can explain this effect and

Highlights of Astronomy, 1983 The purpose of this review is to outline the systematic properties of radio jets on kpc scales, as derived from the basic observations of surface brightness and linear polarization and to emphasize the uncertainties in the determination of their physical parameters. These results come primarily from observations of about 100 jets with the VLA: a fuller

Vistas in Astronomy, 1997 The observational evidence for jets and phenomena arising from rotation powered radio pulsars is reviewed, including many recent and exciting discoveries at X-ray wavelengths. The well studied jets of the Crab pulsar are summarised, including recent results from the HST.

An Old Fogey’s History of Radio Jets
Galaxies, 2017 This paper describes a personal view of the discovery of radio jets in celestial radio sources. The existence of narrow, collimated optical features in distant objects has been known about since the early 20th century; however, the advent of radio ...

The Astrophysical Journal Letters, 2023 Only a tiny fraction ∼1% of stellar tidal disruption events (TDEs) generate powerful relativistic jets evidenced by luminous hard X-ray and radio emissions.

KILOPARSEC-SCALE JETS IN THREE RADIO-LOUD NARROW-LINE SEYFERT 1 GALAXIES [PDF]
, 2015 We have discovered kiloparsec-scale extended radio emission in three narrow-line Seyfert 1 galaxies (NLS1s) in sub-arcsecond resolution 9 GHz images from the Karl G. Jansky Very Large Array.
